Risk-Taking Behavior Among Male Adolescents: The Role of Observer Presence and Individual Self-Control.

A number of studies have focused on the same-sex peer effect on and the developmental difference in adolescent risk-taking in terms of the dual systems model. Little research, however, addresses the effects of different observers, the role of different levels of individual self-control, and their interactions. To fill this gap, the present study examined the main and interactive effects of observer presence and individual self-control on male adolescents' risk-taking behavior with an experimental design. A total of 261 male adolescents (Mage = 15.79 ± 0.79, range = 14-18) completed an adapted Stoplight Task, which measures risk-taking behavior, in the presence of an observer, either peer or adult, either male or female. The results indicated that a same-sex peer's presence and low self-control were both risk factors of male adolescents' risk-taking, but did only low self-control male adolescents take serious risks when in the presence of a same-sex peer whereas those with high self-control consistently had low levels of risk-taking under any condition. An opposite-sex observer, particularly an opposite-sex adult's presence, played a similar protective role for male adolescents with low self-control. The findings suggest that a high level of self-control closely related to the cognitive control system may significantly buffer the negative effect of an adverse social stimulus which activates the social-emotional system on male adolescents' risk-taking; the findings also reveal that an opposite-sex adult's presence may contribute to a decrease in male adolescents' risk-taking by improving their cognitive control system.

Effect of peer presence on adolescents' risk-taking is moderated by individual self-esteem: An experimental study.

Prior research suggests that the presence of peers increases adolescents' risk-taking. However, it is not clear whether the effect of peer presence is moderated by individual characteristics such as self-esteem, since individuals with low self-esteem are more susceptible to peer influence theoretically. The present study examined this problem using an adapted Stoplight Game in an experiment. A final sample of 140 adolescent students aged 14-18 (M = 16.25 ± 0.73 years, 61 girls), divided into two groups-low self-esteem and high self-esteem, according to their self-esteem scores, completed a risk-taking task either alone or in the presence of a same-sex peer. The results indicated that peer presence increased adolescents' risk-taking, specifically for those with low self-esteem, while those with high self-esteem were not affected by peer presence. The findings are helpful for our understanding of peer influence on adolescent risk-taking and the moderating role of the self and have practical implications for preventing and intervening adolescents' risk-taking via increasing their self-esteem.

Does cognitive control mediate the relationship between peer presence and adolescent risk-taking? An ERP study.

Peer presence influences risk-taking behavior, particularly in adolescence. Based on the dual system model, this event-related potential study examined whether and how the presence of a peer displayed a preference for risky behavior would increase adolescents' risk-taking by disrupting their cognitive control processes in either emotional or non-emotional contexts. A sample of 106 adolescents (17-19 years of age) completed two Stoop tasks and a Balloon Analog Risk Task under three peer presence conditions. Results revealed that compared to other conditions, the presence of a risk-averse peer caused adolescents to make safer decisions through improving their conflict monitoring (more negative N200-diff), whereas a risk-preference peer's presence led adolescents to more risky decisions through disrupting their conflict resolution (more positive N450-diff) but they were only observed on the Emotional Stroop task. These findings suggest that different peer presence contexts could increase or decrease adolescents' risk-taking behaviors by influencing their cognitive control under an emotional context rather than in a non-emotional context.
